摘要:: 摘要：催化裂化（FCC）是炼油工业中重要的二次加工工艺，其过程中产生的金属污染对环境造成严重危害。液体钝化剂作为 FCC 的重要组成部分，已被证明可以有效抑制重金属的有害影响，从而提高催化剂的活性和选择性。随着环保法规的日益严格，开发高效环保的钝化剂成为 FCC领域的研究热点。文中综述了重金属的污染机理和钝化剂的作用机理，并对其未来的发展趋势进行了展望。
Abstract: Catalytic cracking (FCC) represents a pivotal secondary process within the refining industry, the metal contaminationgenerated during the process poses a serious hazard to the environment. Passivator, a significant constituent of FCC, have beendemonstrated to impede the detrimental effects of heavy metals, thereby enhancing activity and selectivity of catalyst. In the contextof escalating environmental regulations, the development of efficient and environmentally friendly passivator has emerged as aprominent research focus in the field of FCC. The present study reviews the contamination mechanisms of heavy metals and theaction mechanisms of passivator, whilst also outlining their future development trends.
